ABSTRACT:
A method of forming mufti-phasic nano-objects involves the jetting of two or more different liquids in side-by-side capillaries thereby generating a composite liquid stream. The composite then exposed to a force field which causes the composite liquid stream to at least partially solidify into a nano-object. The method forms a nano-object having a number of morphologies such as rods, spheres, and fibers.
